Functions

func CompilePackage added in v0.17.0

func CompilePackage(moduleName string, pkg *loader.Package, ssaPkg *ssa.Package, machine llvm.TargetMachine, config *Config, dumpSSA bool) (llvm.Module, []error)

CompilePackage compiles a single package to a LLVM module.

func NewTargetMachine added in v0.13.0

func NewTargetMachine(config *Config) (llvm.TargetMachine, error)

NewTargetMachine returns a new llvm.TargetMachine based on the passed-in configuration. It is used by the compiler and is needed for machine code emission.

func Sizes added in v0.17.0

func Sizes(machine llvm.TargetMachine) types.Sizes

Sizes returns a types.Sizes appropriate for the given target machine. It includes the correct int size and aligment as is necessary for the Go typechecker.

Types

type Config

type Config struct {
	// Target and output information.
	Triple          string
	CPU             string
	Features        string
	GOOS            string
	GOARCH          string
	CodeModel       string
	RelocationModel string
	SizeLevel       int

	// Various compiler options that determine how code is generated.
	Scheduler          string
	AutomaticStackSize bool
	DefaultStackSize   uint64
	NeedsStackObjects  bool
	Debug              bool // Whether to emit debug information in the LLVM module.
}

Config is the configuration for the compiler. Most settings should be copied directly from compileopts.Config, it recreated here to decouple the compiler package a bit and because it makes caching easier.

This struct can be used for caching: if one of the flags here changes the code must be recompiled.
